Caution! The machine is dispatched as standard with normal control. On request, the machine can be equipped with a control system that deviates from the norm (eg. with LIEBHERR control). The additional operating instructions for this control system apply in this case. Normal control The left joystick (4) controls the stick and slewing movements. – Direction of movement a and b: Stick is drawn in or out. – Direction of movement c and d: Upper carriage is rotated to the left or to the right. The right joystick (3) controls the boom or bucket and grab movements. – Direction of movement e and f: Bucket will be tilted up or down, grab will close or open.
